SUPPLEMENTARY INFORMATION:

On June 28, 2023, the Postal Service published a notice of proposed rulemaking (88 FR 41871-41872) to add an additional IMpb validation. In response to the proposed rule, the Postal Service did not receive any formal comments.

The Postal Service is adding a third validation under the “Barcode Quality” compliance category that will require that an IMpb must include a valid, unique 3-digit STC that accurately represents the mail class, product, and service combination on the physical label affixed to the package. Additionally, the IMpb on the package must also correspond with electronic package level details and Extra Services Code(s) contained within the Shipping Services File (SSF). Any variance in the data presented in the electronic submission of a parcel or a variance with the physical aspect of the label affixed to a parcel presented for mailing will be subject to the IMpb noncompliance fee if a mailer falls below the 98 percent threshold.

We believe this revision will ensure IMpb quality enabling the Postal Service to provide customers with a more efficient mailing experience.

The Postal Service adopts the described changes to Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM), incorporated by reference in the Code of Federal Regulations. ( printed page 54240)

We will publish an appropriate amendment to 39 CFR part 111 to reflect these changes.

Accordingly, 39 CFR part 111 is amended as follows:

1. The authority citation for 39 CFR part 111 continues to read as follows:

Authority: 5 U.S.C. 552(a); 13 U.S.C. 301-307; 18 U.S.C. 1692-1737; 39 U.S.C. 101, 401-404, 414, 416, 3001-3018, 3201-3220, 3401-3406, 3621, 3622, 3626, 3629, 3631-3633, 3641, 3681-3685, and 5001.
